Bought this book for my son and have now bought it for his friends. Easily accessible for age ten - helps boys generate their own games as well as enjoying how to play them. A really good start for those wanting to think as programmers.
A decent stocking filler - if only it had been packaged properly. Arrived in a flexible envelope so the box and contents were crushed. Toy still works, but is not in decent enough condition to use as a gift for anyone.
